FG

Alarms, Buzzers, And Sirens Overview

The Federal Signal FG is a flush-mount grille cover plate designed for use with specific electronic horn and siren units, including the Vibratone 450E and 350 series. Constructed from steel and finished in gray, this component serves as an aesthetic and protective enclosure for the internal signaling mechanisms. It is engineered to mount directly into plastered-in FB flush boxes, providing a seamless integration with wall surfaces. The unit measures approximately 6 inches in height and width, ensuring compatibility with standard installation dimensions for these audio signaling devices.

Alarms, Buzzers, And Sirens Procurement Notes

Verify exact model compatibility before purchase, as Federal Signal uses similar part numbers across different product lines. Confirm whether the required application involves the 350 or 450E series, as grille specifications may vary slightly between these models. Ensure the installation environment supports flush mounting into standard plastered boxes. Check for any regional variations in housing materials or finishes if sourcing internationally.

Alarms, Buzzers, And Sirens Selection Notes

Select the FG grille only when replacing a damaged or missing cover for compatible Federal Signal horn units. This part is strictly a cosmetic and protective grille, not a functional signaling module. Do not substitute with generic grilles unless they match the precise 6-inch square dimensions and mounting hole patterns. Verify that the underlying horn unit is operational before installing the new grille.

Alarms, Buzzers, And Sirens Part Context

The FG is a mechanical accessory within the Federal Signal audio signaling portfolio. It belongs to the family of replacement parts for industrial and commercial warning devices. Unlike the RSL-LMM-F-G radiant light module, which provides visual signaling, the FG is purely structural, serving to house and protect the acoustic components of the associated horn systems while maintaining architectural aesthetics.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include Federal Signal part numbers specifically designated for the 350 or 450E series grilles. Ensure the replacement matches the original steel construction and gray finish to maintain consistency in industrial settings. Generic alternatives are not recommended due to precise mounting requirements.
